Products Description of Ammonium Molybdate CAS#13106-76-8
Ammonium molybdate is a colorless, white, or slightly greenish-yellow powder. It is primarily used in chemical analysis for the determination of phosphorus. When dissolved in a nitric acid solution, it precipitates phosphorus as ammonium phosphomolybdate with the formula (NH4)3PO4·12MoO3 after drying at 110 °C (230 °F). Certain phosphomolybdic acids derived from it are also utilized as reagents for alkaloid detection and for the analysis and separation of alkali metals.
